BINDING DEVICE FOR PANEL-BOARDS.

' Application filed March a, 1911.

tions and constructions hereinafter set forth and claimed.

In describing this invention reference 18 had to the accompanyingdrawings in which like characters designate corresponding parts in allthe views.

Figure l is an elevation partly in section, panel board embodyingmydnvezition. Fig. 2 is a sectional view of such panel board showing oneof the terminals in section and another terminal in elevation.

1 is the base of the panel board which -may be of any desirable form,size and construction.

I and 3 are respectively sets of conductlng bars, the bars of each setbeing arranged one above the other when the panel board is in horizontalposition and supported by suitable pillars -1 which include spacingrings 5 of insulation located between the bars. The sets of bars 2, 3extend parallel to each other and the individual conducting bars areconnected, respectively, in different circuits as meter circuits.However, one set of barsmay be omitted if desired.

The terminals are arranged about mid way between the bars .3, 3 and arecon nected to bars 6 which are in other circuits than the meter circuitsand are connected to corresponding sides of the load circuits, theopposite sides of which are connected to bars '7 in circuit with themain conductors of the panel board. he arrangement of the circuitsconnected to metering panel boards is well known and further descriptionherein is unnecessary as this invention relates in no way to suchcircuits. However for a full description reference is made to my pendingapplication, Sr. No. 585,598.

Specification of Letters Patent.

these sleeves of-insulation Patented Dec. 1, 1914. Serial No. ($13,209.4

meter circuits by a connecting member 8 to be described. Each terminalcomprises a post including a plurality of spacing rings 8) arranged oneabove the other around a suitable support 10, any two of the spacingrings being adapted to receive a. connecting member 8 between them; anda sleeve 11 of insulation encircles the spacing rings and supporttherefor, and is formed with a plurality of transverse slots 12 in oneside thereof for exposing the edges of the abutting end faces ofcontiguous spacing rings 9.

In my application 585,598 referred to, are shown as formed of aplurality of rings, one insulatmg ring for each spacing ring, but theconstrliction shown herein is much more simple as 1t requires no fittingtogether of the various rings composing the insulating sleeve. Asillustrated, the sleeve 11 is composed of two sections, the uppersection bemg provided with the slots 12 and the lower section restingdirectly upon the block 13, presently described. Each terminal may be ofany desirable form, size and construction and as here shown, itcomprises a base block 13 l of the panel board, ametallic internallythreaded sleeve 14; mounted above the block 13, a clamping member, as ascrew 15, extending through the base 1- of the panel board from therear-side thereof, through the block 13 and threading into the. lowerend of the sleeve H, the support 10 which is a screw threading into theupper end of said sleeve, the screw 10, one above the other, thelowermostnormally resting on the sleeve 14, and a nut 16 turning on theupper end of the screw 10 against the uppermost ring 9. The

movement of the nut 16 outwardly is limited by the head 17 on the screw10,1such head 17 permitting suflicient movement outwardly of the nut toallow the spacing rings to be separated sufficiently to permit theinsertion of but one of the connecting members 8 between adjacent rings,or between the lowermost ring and the sleeve 1%. When the slots 12, inthe sleeve 11, face one set of conductor bars, as the bars a connectionmay be made by a member 8 between a bar of that set and the part of theterminal having electrical conductivity. and at the same time the intactpart of the sleeve is presented to the other mounted on the base'spannenare setdfbarseas the bars. 2', for preventing the w-bility'ofa-connection bemg made one of-"the'same' and the termiznal. Theterrdi'nals a'rebracedat their .outer ends iby' -or spanners, 20, one

--being preierabgsassociated with two conpanionfapplicati''nhereinbefore referred to.

.As-here1. shown, the -opposite ends of a tojthe pillars. 4 and themiddle part of the s provided with s'eparated. openings 13 which receivethe sleeves 111. rTheupper end-of each sleeveis preferably provided"witha shoulder 18 overhanging the edge of the opening through Whi hjth esleeveexten'ds. A'set f'screw 21".is preferably provided for prevei'ting the aecidentahturning'ofi the sup- *port 10' in referenceto thesleeve 14.

' The end portion-22 of each of the bars 6 is'oflset from the base 1,overlies and is .usually-sunk into the upper end of the blOeklB ispierced-by .the screw 15, and the sleeve 14 is seated on saidport1on'22'1n' electrical contact. therewith.

.The connecting member 8 1s l here shown as of substantiallythe sameconstruct on as that shown and: described in my pending application585,598 referred to, said member'being formed-of astrip of metal bentupon itseliat-23 'inorder to'form spring jaws" forembracing oneof thebars 2 or one of the "arms as 2d of the strip being "longer than theother and having a bifurcated end 25 adapted to be inserted through oneof 'the slots 12' between two of the spacing rings 9 or. between thelowermost spacing. ring 9 and the upper end of the sleeve 14L, asclearly shown in the drawings.
